Abstract: A method and apparatus for offering multiple switch access to selected lines and trunks of a multiple telecommunications switch complex. The selected lines and trunks are connected to peripheral units whose outputs are distributed by a network to a group of switches. The switches are interconnected by a second network. Advantageously, the selected lines can be served by several switches so that the failure of one switch does not deprive these lines of service. Advantageously, the two networks and the group of switches form a giant switch having high reliability.

Abstract: A distributed object oriented computer system that has two classes of object references: strong references and weak references. Weak references (or pointers) allow users to refer to an object, but does not prevent the object manager from deleting the object. A weak object reference can be converted into a strong object reference by execution of a "MakeStrong" operation, which generates a strong reference, and then deleting the weak reference. A strong object reference can be converted into a weak object reference by execution of a "MakeWeak" operation, which returns a weak reference to the object referred to in the operation's argument, and then deleting the strong reference. When an object no longer has any outstanding strong object references, deletion of the object is enabled. In another aspect of the invention, a portion of the computer's memory is set aside for a primary linker cache and a secondary linker image cache. Linker images, generated while loading programs for execution, are stored in the primary and secondary linker caches. Each linker image in the primary linker cache has strong object references to objects included in corresponding ones of the loaded programs, and each linker image in the secondary linker cache has weak object references to objects included in corresponding ones of the loaded programs.

Abstract: An ink-jet bottle and valve system (10) delivers ink-jet ink (12) to an ink-jet printer apparatus (30) having an ink reservoir (32). The system has five, main components: a bottle (20), a housing (80), a valve (120), a cover (150), and a vent tube (180). Coupled to the ink reservoir, the housing has a nozzle (82) which extends into the ink reservoir and defines a channel (84) through which ink may flow from the bottle to the ink reservoir. The top surface (98) of the housing has a cutout (100) defining a pair of valve rotation stops (102, 104). The housing also has a bottom surface (96) which includes a lower vent (106) and a lower ink passage (108) each opening to the channel of the nozzle. The valve fits and rotates within the housing. The internal surface (128) of the valve is threaded (130) to couple the valve to the threaded neck of the bottle. The bottom surface (126) of the valve has an upper vent (136) and an upper ink passage (138). Finally, a top surface of the valve has a projecting tab (142). The tab rests in the cutout of the housing and cooperates with the valve rotation stops to limit axial rotation of the valve within the housing between (i) a first position where the tab abuts one valve rotation stop and in which the upper vent and the upper ink passage of the valve align with the lower vent and the lower ink passage, respectively, of the housing, and (ii) a second position where the tab abuts the other valve rotation stop and in which the upper vent and the upper ink passage of the valve are out of alignment with the lower vent and the lower ink passage. The cover engages a flange (86) on the housing and captivates the valve within the housing. Finally, the vent tube allows air, required to equalize the pressure in the bottle, to pass directly to the area (182) at the top of the bottle above the ink and assure even ink flow.

Abstract: The present invention discloses a signal amplifier
circuit used in, for example, a receive portion in an
optical communication system, and including an automatic
threshold value setting portion (2) to automatically set
a threshold value depending upon a "1" side level and a
"0" side level of an input signal, an automatic gain
control amplifying portion (3) to take as inputs the
input signal and the threshold value from the automatic
threshold value setting portion (2) so as to perform
differential amplification, and a gain control portion
(4) to detect amplitude information of the input signal
so as to feed a gain control signal according to
amplitude of the input signal to the automatic gain
control amplifying portion (3) as a feedforward signal.
It is thereby possible to avoid limitation of a signal
amplified in the signal amplifier circuit at a time of
reproduction of a pulse signal, and compensate for
offsets present in circuits so as to suppress a variation
in pulse width of the output signal.

Abstract: A vacuum cleaner head, for attachment directly to a vacuum cleaner body having a central longitudinal axis, has exposed bristles with remote ends on a plane off-set by about 70° to the central axis. The bristles 14 and IS extend along opposing sides of a lower surface of the head in strips at either side of a channel 18 through which dust and debris gathered up by the bristles passes into the vacuum body. The off-set plane means that when the body is held directly or by a handle, a natural comfortable sweeping action, with the handle axis at about 20° to the vertical, keeps both strips of bristle in contact with the swept surface.
